third than to humeral cross-vein ; cell formed at furcation of third vein 
long, the second vein ending almost as close to the first as to the 
third ; fourth vein curved on basal one-third, then straight to the 
recurved tip ; fifth nearly straight ; sixth faintly bisinuate ; seventh 
distinct. Halteres with the capitulum piceous and pedicel testaceous. 
One female from Friedrich- Wilhelmshafen, New Guinea (Biró, 
1896). 
This species is recognizable by its smooth front without ocellar 
tubercle or groove, in connection with its other characters. 
Aphiochæta crassimana n. sp. 
Male. Length 1*5 mm. Black, the palpi and anterior metatarsi en¬ 
larged. Head rather small, with strong bristles. Front slightly wider than 
long, very shining, with sparse strong punctures ; ocellar tubercle and 
frontal groove well marked. The four proclinate bristles close together, 
the upper ones low down and approximated, forming together with the 
lateral pairs of the row above a curve following the anterior margin of 
the front ; following row straight, close to the ocellar row. Antennae small, 
oval, piceous black; the arista pubescent; post-ocular cilia delicate, the 
posterior margins of the cheeks with several small macrochætæ on each 
side. Palpi black, much swollen and projecting, provided with only very 
fine bristles below at base, but with several of the normal size apically. 
Dorsum shining piceous black, with a single pair of dorsocentral macro¬ 
chætæ and two scutellar bristles. Abdomen dull black, hypopygium small, 
directed forward under the abdomen. Legs dark browm, the anterior pair 
a little lighter basally. Anterior femora considerably swollen basally, and 
furnished with a groove for the reception of the tibiae which are also 
stouter than usual; front metatarsus enlarged and flattened, as wide as 
the tibia and fringed on its inner edge with microscopic bristles ; other 
tarsal joints flattened, almost as broad as long. Middle and posterior legs 
moderately stout, the hind tibiae very finely setulose, almost smooth. Wings 
clear hyaline, the costal vein not quite attaining to the middle of the 
wing, its bristles rather long, fine and closely placed; tip of first vein 
distinctly nearer to the tip of the third than to the humeral cross-vein ; 
furcation of third vein obtuse, the second vein almost perpendicular to 
the costa ; fourth vein very slightly curved, recurved at the tip ; fifth 
nearly straight ; sixth distinctly sinuate ; seventh distinct. Halteres 
black. 
Described from a single male from Botany Bay, Sydney, New South 
Wales, Australia (Biró, November 1900).
